Abstract

The invention discloses a directed cultivation method for a drought-resisting water-saving variety of winter wheat. The directed cultivation method mainly comprises the following steps: A, selectively pairing and hybridizing excellent complementary parent materials; and B, carrying out directed cultivation to select a new strain with strong drought resistance and high yield, wherein the step B iscarried out according to the following operations: B-1, planting early-generation F1-4 materials under high water and fertilizer conditions, and selecting based on yielding ability; and B-2, taking higher-generation materials (above generation F5) in duplicate, respectively planting under high water and fertilizer conditions and drought stress conditions in an inter-generation water-drought alternation manner, and selecting the new strain with strong drought resistance and high yield. The selected new variety of winter wheat has outstanding drought resistance and water-saving property, and has the characteristics of high yielding potential and strong stress resistance.

Description

technical field

[0001] The invention relates to the technical field of breeding of new varieties of crops, in particular to a comprehensive selection technology for drought-resistant and water-saving varieties of winter wheat in different generations of alternating flood and drought directional cultivation. Background technique

[0002] Wheat is one of the main food crops in my country. The perennial sown area is 340 million mu, of which the northern winter wheat area is 276 million mu, accounting for about 60%. In this area, the south of the Great Wall of Hebei, the middle and eastern part of Shanxi, the Yan'an area of ​​Shaanxi, Ningxia, Xinjiang, and eastern Gansu have an annual planting area of ​​nearly 100 million mu. This area is located in arid and semi-arid areas, and 50% of the wheat fields are not irrigated. Wheat fields and dry wheat fields have high and low yields and poor yield stability. The main factor affecting it is drought and water shortage. The lack of wat...
